Has anybody else's toddler started going cross eyed? I'm freaking out 😭

Our 3 year old has been going cross eyed the past few days and I'm freaking tf out. Of course I'm dumb and Google search everything and it shows brain tumor, etc. 😓😵 Has anybody else had a similar experience? What was the outcome/solution? I attached a picture of him tonight while he was eating/watching tv. This was the best picture I could get because he hides if he sees me trying to take a picture. It looks way worse in person. 😟 My anxiety can't handle this.
